Two and three bar MAP sensors are available and allow the 950 TBI units to be used in conjunction with supercharged applications.

A Demon of a Carb
The Road Demon Jr. is the perfect replacement carburetor forentry-level, general-performance engines in cars and light trucks. The Road Demon Jr. is offered in three sizes for engines with smooth idle characteristics: 525 cfm, 625 cfm, and 725 cfm. The Road Demon Jr. carburetors utilize a side-hung float design, allowing use in applications where clearances may be a problem. The design gives it the hallmark "Demon appearance" in a more compact form. Other features include vacuum secondaries; a primary float bowl with large, EZ-Safe sight glass for safe float-level adjustment; two- corner idle adjustability; a large, trouble-free fuel-transfer tube with dual-captured O-ring sealing; built-in Power Valve blow-out protection; and two constant and one ported vacuum outlets. Each carb is wet-flow tested and baseline calibrated at the factory, and is shipped with a detailed tuning manual. An optional choke kit is available. Send $5 for the latest catalog/technical manual.

The Next Big Thing
Crane Cams' state-of-the-art HI-6DSR Dual-Stage Rev Limiter CD features multiple rpm limiters and a higher spark-gap current than comparable digital ignitions. This improves performance for race or street engines in excess of 14.5:1 compression ratios (or in turbo and supercharged applications). The dual-stage rev limiter can be preset from 600 to 9,900 rpm using big rotary switches instead of chips. Built-in flashing codes take the guesswork out of troubleshooting. The ignition box continuously checks for problems in the coil, ground, power supply, wiring, and box. It even checks tachometer accuracy. Crane Cams; 386/258-6174; cranecams.com
